Ok, bear with me.
When I had my HTC Touch Pro, I remember the gps program I used would sync to a number of different satellites and switch between them based on different times of the day, signal strengths, etc...
I know that I have read many people saying that their position on gps is off by about 50 to 100 yards most of the time, and nothing they do can correct this.
I know that with the current set of ROM's out there, I am wondering if some of using different satellites to connect to, which because of the position of those satellites may be causing this.
Does anyone know how to check which satellites any specific ROM uses when checking its position using the gps? If different ROM's (from different countries possibly) are using different settings, are they settings we can alter or change to correct this or make our locations more specific? I am relatively sure that the phone uses the network tower location as well as wifi signals to better set someones location on a map, but is there a way to better define where a specific phone is located?
(Note: I did a search or 12 and didn't find anything like this in this forum for the Hero, if you have something informative or relative to say, please be nice about it. Thanks for your input!)
i would think that the actual signal handling is done in the gps chip itself, the android os gets the position "told" from the chip once it is calculated, it also gets the signal strength told.
you can check the satellites and signal with free "gps check" from market.
The gps is based on geo-synchronous satellites. The accuracy is based on the algorithm used and the number of available satellites. There are offsets to reduce accuracy which are imposed to limit the military uses. There are sync points to known objects (towers) which allow refinement.
The time lag of the gps receiver radio could, if it were designed wrong , affect the accuracy, but not likely since most likely it stores the time difference to the clock, asynchronously. ( a guess)
You can get more accurate software (wasp) . My marine unit gets me to 10 meters. I can usually find stuff 35' away. lol
So to answer your question, I don't think roms unless they changed the kernel affect the accuracy.
I guess there is a chance that the ROM has set the GPS to look for certain satellites by default, thereby causing some confusion, but I'm not sure that is the issue because my GPSr seems to be pretty accurate unless I am navigating with Google Maps at high speeds. I was thinking maybe it was a speed issue of sorts.
That said, here are some grabs of the satellites I'm seeing using DamageControlv2.05 (and the GPS Test app):

Well, I agree with most of what you are saying, however, I think part of it is retrieving the signal from the gps chip, and I think part of it is the software on the phone is taking that information and combining it with the location information from triangulation with towers and its throwing off the location a little. Outside, with a clear sky, no buildings blocking me, and on the map (using satellite or map layers, I am still about 100 feet away from the map location. I know others have complained about it. I am just wondering if there is something in the ROM or software that might be causing it.
First, read up on aGPS, and how that works. Most people seem to think that it's a cheap, dumbed down, "pseudo-gps"... That's not true at all. aGPS is complete, fully capable GPS with extras that it can use to enhance both speed and accuracy.
A few of the things aGPS does to speed up the inital lock, though, can mean that the position is less than accurate for the first minute or two, until it acquires a full blown lock from the satellites.
When properly implemented, aGPS should be *better* than just regular GPS. There is room in there, however, for a programmer to screw up when coding an algorithm or two and actually throw things off. I'll admit that I would have thought that this would have all been handled on the GPS chip, but now that I think about it more, it's very possible that some of the logic is done by the software on the phone, and that could change between software versions.
Still, that's not the sort of code that rom devs are changing, so any inaccuracies caused by the software should be consistent between the various roms based on the same Android version....

Hello, sup?
I'll start with my intention, my dad is building a library of photos for documenting the cities. He wants to capture where the photos were taken and the problem is that our camera doesn't have a GPS addon available. So we found one solution, we can use Google's "My Tracks" to track his paths and then patch them into the photos using a software. Now we don't got 3G networks in our providers(2 providers got but we don't use them), only EDGE.
I'll be getting my SGS tomorrow(hopefully, the previous one had 3 buttons download mode disabled and I bricked it) and we won't be taking it if it doesn't have the 3 button combo working. So I'll be probably flashing JPC to improve the GPS, now my question is would it be reliable enough on an EDGE network to track his movements for about 4-5 hours? Also, does the speed of data connection make a difference in the reliability of tracking?
Just for the record, the camera supports GPS location written to the image EXIF. Basically it should (in theory) attach the location where the image is taken to the image metadata.
it's not necessary to have 3G or EDGE to use the my tracks GPS software from google
you can still record tracks, and download the tracks to SD card
then when you get home just swap the SD card to your PC and then upload the Data at home

I know that, but the camera would not be able to capture the quality of our camera or take 360 degree panoramas.
Well then you can either use My Tracks (as AllGamer says, you don't need edge/3g), or you can still take a mobile camera photo for every time you take pictures with the other camera, so that you can just match the photos taken on the same location later on, and take the GPS info from the camera photo.
Thanks for your advice , would My Tracks with GPS on SGS be reliable enough to keep the recording on for 4-6 continuous hours?
4 to 6 hours is no problem, specially if you are not using wifi/3g when exploring the paths
It mostly depends on what shape your GPS is in. As you might have read, the GPS on the SGS can be pretty unstable and inaccurate, but some people seem to not have this problem (AllGamer is definitely one of them). Samsung has announced a fix to this problem which should come in the froyo update at the end of this month.
If you look around this forum you will see that many people are having problems with GPS. Galaxy is a great phone but is not reliable as a GPS device. If GPS is very important to you you are better of getting another Android phone such as Desire

According to most people, GPS accuracy is not very high on the SGS, but personally I haven’t had many problems with it myself. I use it mostly while driving where accuracy is pretty good, but while on foot it tend to jump around a bit but still pretty ok.
GPS has a heavy toll on the battery, and we all know SGS doesn't have a good battery life to begin with (especially if the screen is used a lot), IMO it wont last 4 to 6 hours of continuous use, you might have to take a spare battery.

Even though SGS has a decent phone camera, image quality is no where near to even an entry level compact. I don't think anyone would be interested in using it for documentary purposes. OP was asking how to use his phone's GPS to get coordinates and sync them up with photos taken with a separate digital camera.

Ask them what problem was found, was it related to software or hardware?
Its mostly the settings which might need tweaking as per your location. I have noticed that 1st time gps locking takes time & you should have working data connection to assist its locking & after that the phone maintains a cache of your locations.
GPS dont work indoors so go out in open park 50mt away from the nearest buildings & switch on the gps & see if it locks or not. Indoor the phone uses cell tower to determinate your location but gps wont lock your location due to missing signals.
These are my settings.
menu>settings>Location & security>
check all with green check mark.
use wireless network
use gps satellites
use sensor aiding
Might help to lock, try these & report back.

5 mins = 7- 11 sats on a cold boot for me .

Did you tried a diffrent modem? Like JQ1 or something. Maybe that help.
I've tried several firmwares with different modems, all of them gave the above result outdoors, still after 10-15 mins waiting. The settings are the best touted around the web, also tried FasterFix... no luck.
I really suspect a HW failure or something with the antenna. The SNR value starts off at around 30-35 when the device senses the satellites, then slowly goes down to 14-18.

I had exactly the same problem with GTI9003 fw DDKB2. I tried all the softwares which you tried and results were exactly same. No settings worked. So I changed to XXKB3 available in forum. The GPS worked instantly without having to change any settings. I have tried this on two different pcs and it works. So you can try this fw and let us know the results.

After updating my trusty S4 Active i9295 from 4.2 to 4.4, I found the GPS to be less reliable than before, and sometimes take quite a long while before getting a lock.
Further investigation of this heinous issue revealed to me that no GLONASS satellites are in use:

I have NH2 modem flashed. In GPS Test i can see few triangles active (help statest that triangles are GLONASS satellites). GPS Toolbox also shows two kinds of items, green circle and grey box. Apparently it's working?
Now this is really odd. No matter what I tried earlier today - I couldn't "connect" to any glonass satellites. Sygic, GPS Status as well as GPS test were showing the satellites but no signal. After reading your answer I tested again. Instant fix and at least three glonass satellites... Still NE5 firmware - seems like I have to keep an eye on it for a few days... Hopefully it was just glitchy once

What is the fix ?
GLONASS still does not work with NH2 firmware.

for your responsibility.
Files from i9505 ROM (Omega v37)
For a bit better fix look for my thread in development forum.
Some, not critical AGPS related framework changes also merged from 9505 to my mega pack.
Solved
After updating my S4 Active to 4.4.2 the Glonass satellites were not locked anymore.
Now my son bought a second hand S4 with 4.4.2 already installed and surprisingly Glonass satellites are locked.
I copied the file system/lib/libloc_api_v02.so (same size) to my phone, and tada, I have Glonass satellites locked!!!!!!
So I'm pretty sure it is a bad file copied by Samsung in the ROMs and not a KitKat bug.
See attached rar-file from another thread which put me on the right track.
The 7z-file is the one that worked for me, didn't try the the rar-file.
Thanks to the poster of the file.
Just unzip the file and copy it to /system/lib and reboot your phone.
Thank you very much!!
Finally getting GLONASS fix again Much faster
Thanks Foresterawd
I got a strange thing. After replacing the libloc in system\lib, my GPS position is 50 metres to far south...
Although the accuracy is 3metres.
Now I changed the gps.conf in system\etc too and now my position is 50 metres to far north...
What could this be?
EDIT: After restarting, the position is correct with the new gps.conf
For those who have downloaded the OTA Lollipop update or installed the moforoot Lollipop ROMS-Have the WIFI lag/issues been fixed?

It causes your phone when your on wifi to intermittently stop loading whatever you were doing i.e. loading a picture, a website, etc. Then you either have to hit refresh several times for the page/picture to load or switch back to 4G.

I can say that it 100% fixed this issue for me. I am one of the folks who seemed to experience this almost all the time and was eagerly waiting to see if this problem would continue to plague me after 5.1. I used moforoot and am running v1.0 of computerfreek's LP image. I haven't flashed v1.0B because I read some comments about flaky 4G/LTE reception and I live in a sort of 3G/4G fringe area. I am very pleased with my LP experience so far.

It fixed it for me as well. That was my biggest ***** about the turbo and yes I *****ed about it a lot. I have had not one problem since. And previously I tried turning IPV6 off and it made no difference. At least on the 3 routers I tried. Currently IPV6 is on and I have no issues.
For sure it is the IPv6 in your router. I had the issue with 2 phones before I was able to figure it out and the second I disable IPv6 the issues went away permanently.

In spite of the tech hype about IPv6, it's not necessary for people who use a cable/telco ISP for internet access.
And IPv6 still has several security issues for people who just have it turned on without proper protection against IPv6-based malware due to Teredo tunneling (backdoors into your system).
Should I Disable IPv6?
http://www.wilderssecurity.com/threads/should-i-disable-ipv6.358189/
My home router runs a mini version of DD-WRT which does not offer IPv6 access/support, and I keep it that way on purpose. "Regular" (larger) versions of DD-WRT do offer IPv6, but you can disable it:

I have also disabled IPv6 on both my personal Windows desktops for good measure.
When I run this test, I have IPv4 only and that's how I want it, for now.

This could also be cause by dhcp leases. I have seen long wait times dor dhcp ipv4 with a bang next to wireless. I reserved the ip and issue resolved.
Well I finally made the jump and flashed from Computerfreeks's KK to his LP rom yesterday...
...and my wifi lag issues seem to have all been fixed. I forgot how fast your home wifi can be! "(insert sarcastic laugh). I didn't make any changes to my router either. So maybe that is one of the hidden reasons it took so long to get this update out.
Hope this helps some other people.
Hi guys, I replaced my rear camera and the loudspeaker on my OnePlus 3T an they works well.
The problem is that now WiFi, Bluetooth and GPS don't work (no networks are detected).
I noticed that if I'm really close (1meter) the access point network is detected and I'm also able to connect but with very poor signal strength. The same with bluetooth (10cm). Also GPS does not acquire position.
I think the problem is related to the antenna. I opened my OP3T different times to check if something is wrong but I couldn't be able to figure out what is the problem.
Did someone face this problem?
Thanks in advance.
Hi guys, I tested GPS and it works. So the problem is related to WiFi and Bluetooth. Does someone know what are the pins in the mainboard that connect WiFi circuits to antenna? Without back cover with integrated antenna, should the WiFi normally find some networks? Thanks.

I think it could be a missing resistor.

If you look at the image it seems that in that position there's a small black resistor.
What do you think? Is that area the one related to wifi circuit (and antenna)? Thanks.
Hi,
I am facing the exact same problem with my OP3 (no WIFI, no bluetooth, GPS working fine) after changing the battery. I precisely compared my phone with the picture you took on internet and I do have exactly the same configuration (I have the small black resistor).

- The BT/WIFI chipset is located on the top right of the phone, but under the metallic protection.
- The BT/WIFI antenna is located on top left of the back cover. I guess the connection between the antenna and this chipset is broken somewhere
I'm sorry I didn't provide any image, the forum doesn't let me post images since I am new here
It would be interesting to understand if without back cover normally wifi works (obviously without a strength signal).
Because this way we could figure out if the problem is related to the antenna placed on the back cover (or to the pins that connect it to motherboard) or is related to the motherboard itself.
Thanks guys.
I have this same problem, I tried to pick up pins on motherboard, but it doesn't change anything. Probably something is wrong with back cover.
Has someone found a solution for the issue? I noticed even my phone's hotspot has a weak signal similar to wifi and bluetooth. I'm using my OP3 without wifi or bluetooth for almost 4months now.. Any help is appreciated
Im having the exact same issue after replacing a motherboard, did anyone find the cause?
Hi,
I am having issues with my WIFI and BT signal too. My WIFI signal is ok up to 1 meter and my BT signal up to 30 cm.
Today, after opening my OP3 i've notice something in the back cover. Apparently something was broken. I closely looked at it and noticed it was whiteish some kind of resistor on the top right corner of the motherboard. It was broken and missing from its place.
With me this is probably the thing that is causing the problem.
Just for curiosity purpose, I've opened my OP3 once again and removed the antenna cable. It turned out with or without it it does not make any difference for the signal strength.
Hi,
Do we have any resolution on this issue?
